根据滚动位置触发视频自动播放 [英] Triggering a video autoplay based on scroll position

问题描述

我正在编写一个使用scrollorama.js脚本中的Wipe动画的脚本。我希望能够在滚动深度中的某些标记处实现视频自动播放：即，当视频页面消灭了另一个时，现在可以完全查看。我已经弄清楚如何测量滚动深度，我已成功将其记录在我的控制台中。我已经弄清楚如何测量我滚动的深度，但也许我很累，我不知道如何让视频在滚动深度自动播放。我希望这是一个法律问题，我可以得到一些帮助。之前有没有人试过这个？这是迄今为止的代码。

I am writing a script that uses the Wipe animation from the scrollorama.js script. I am hoping to be able to implement a video to autoplay at certain markers in the scroll depth: ie, when a video page has wiped out another, and is now fully viewable. I have figured out how to measure scroll depth, i am successfully logging it in my console. I have figured out how to measure how deep i have scrolled, but maybe i am so tired, i don't know how to ask the video to play automatically at the scroll depth. I hope this is a legal question, and that I can get some assistance. Has anyone out there tried this before? Here is the code thus far.

在此处输入代码 $（document）.ready（function（）{

enter code here $(document).ready(function() {

$（窗口）.scroll（函数（e）{

$(window).scroll(function(e) {

  var scrollAmount = $('body').scrollTop();
  console.log(scrollAmount);

}）;

    var controller = $.superscrollorama();
    var pinDur = 800;   
    // create animation timeline for pinned element
var pinAnimations = new TimelineLite();

//pinAnimations.append([TweenMax.to($('#green'), .5, {css:{top:0}})], .5)
pinAnimations.append([TweenMax.to($('#intromovie'), .5, {css:{top:0}})], .5 )
pinAnimations.append([TweenMax.to($('#red'), .5, {css:{top:0}})], .5) 
pinAnimations.append([TweenMax.to($('#blue'), .5, {css:{top:0}})], .5 )
pinAnimations.append([TweenMax.to($('#movie1'), .5, {css:{top:0}})], .5);
pinAnimations.append([TweenMax.to($('#history1'), .5, {css:{top:0}})], .5);
//pinAnimations.append(TweenMax.to($('#pin-frame-unpin'), .5, {css:{top:'100px'}}));


controller.pin($('#content_wrapper'), pinDur, {
    anim:pinAnimations, 
    onPin: function() {
        $('#content_wrapper').css('height','100%');
    }, 
    onUnpin: function() {
        $('#content_wrapper').css('height','1000px');
    }


});

});

推荐答案

我想出来了，所以我回答了我自己的问题在这里拼凑了许多其他答案的帮助！

I figured this out, so i answer my own question with the help of a lot of other answers patched together here!

如果有人有兴趣，html很简单：

If anyone is interested, the html was simple:

    <div id="videoHolder"></div>

Jquery也很简单：

Jquery was also simple:

        $(function(){

    $(window).scroll(function(e) {

        var scrollAmount = $('body').scrollTop();   
        console.log(scrollAmount);


    if(scrollAmount >="theamountyouwant" && scrollAmount <= "theotheramountyouwant") {


        $("#videoHolder").html(
            '<video width="1200" height="700" autoplay>' +

         '<source src="http://itp.nyu.edu/~rnr217/HTML5/Week3/video/testopen.webm" type="video/webm"></source>'  +
        '<source src="http://itp.nyu.edu/~rnr217/HTML5/Week3/video/testopen.mp4" type="video/mp4"></source>' +

         '</video>');
